Hi, I've discovered that most of the user's mailbox size is unlimited. I want to run the powershell where it should set every user mailboz upto 2 GB except few users (MD/GM etc). How can I achieve this? thanks

You can set mailbox quota on all databases instead of doing it on all users to manage it at central place.How to Configure Storage Quotas for a Mailbox Databasehttp://technet.microsoft.com/en-us/library/bb201753.aspxFew users which you want to exclude, you can set blank value on their individual quota on mailboxes so they don't have any limit.How to Configure Storage Quotas for a Mailboxhttp://technet.microsoft.com/en-us/library/aa998353.aspxReference Thread:http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/fdb60cf7-1baa-4ff0-9ebd-0ec9b84afe4b/Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
